Lamb to the slaughter Essay Example

Lamb to the slaughter Essay Dr Watson is not as observant as Holmes when studying the clues because Sherlock is in deep concentration when studying Stoke Moran whereas Dr Watson is just watching him and not looking at anything for clues.  Ã‚  We had walked several times up and down the lawn, neither Miss Stoner and myself liking to break in upon his thoughts before he roused himself from his reverie.  When Sherlock and Watson are sitting in the room where Julia died waiting for something to happen Dr Watson is quite tense and when something does happen Holmes keeps his cool and hits the snake whereas Watson doesnt really have a clues what is going on. Watson is blinding by the sudden change from complete darkness to sudden light. He only finds out what has fully happened when Holmes and himself enter Dr Roylotts room. When we read Lamb to the slaughter and studied the detectives in it that we found that they were very unlike Sherlock Holmes and Dr Watson. Detective Noonan is from the regular police force and comes to the crimes scene and doesnt investigate every possible suspect because he doesnt interrogate Mrs Maloney and therefore does not come across as a very good policeman who suspects everybody unlike Sherlock Holmes. Detective Noonan also doesnt come across as professional as Sherlock Holmes and Dr Watson. You can tell this because Noonan excepts some whisky which is very wrong because if he had been found out he would most likely been fired. Noonan also has some food, which is also wrong and it is also the murder weapon so there would be no chance of finding out that Mrs Maloney killed her husband.

Also it doesnt take much questioning to the green grocer to rule Mrs Maloney out. The detective was only at the green grocers for fifteen minutes and that was it.  In fifteen minutes he was back with a page full of notes.  Detective Noonan was exceptionally nice to Mrs Maloney, which show yet again that they are not very broadminded and dont suspect everyone. The police should fully investigate Mrs Maloney. Sherlock Holmes is very polite towards people who ever they are. Detective Noonan doesnt come across as being very polite because he belches when he is eating the leg of lamb, which is very rude and impolite, Holmes, would never do this.  There is another detective in Lamb to the slaughter named Detective OMalley. This detective is not much different to Detective Noonan and totally different as Sherlock Holmes and Dr Watson. He also doesnt come across as very intellectual, unlike Holmes. You know this because he eats the murder weapon and is saying that he thinks the murder weapon is right under their noses, which it is. He also doesnt appear to be professional at his job because he also eats the murder weapon and he drinks the whiskey. He is also exceptionally nice to Mrs Maloney, which means that he also isnt inspecting every angle of the case. There are more detectives on the case in Lamb to the slaughter than in The speckled band which is an advantage. They have a photographer and forensics to help the case. They could get time of death what instrument killed Patrick and so on, this would have helped to solve the case but they didnt. Sherlock Holmes didnt have any of these but still managed to solve the case. This shows that the detectives are no where near as clever as Holmes and Watson.  When we looked at each storey we studied the crime and the motive in each story and compared them to each other, we found that the crimes and motive were very unfamiliar whereas in each story there was a murder involved. In The speckled band the murder was very carefully planned, an air vent was installed so the snake could pass through into the next room from Dr Roylotts room. Bell pull was put in next to the vent so that the snake could climb down onto the bed where Julia was sleeping. The bed was clamped down to the floor so the girl was unable to move the bed away from the vent and bell pull.  The bed was clamped to the floor the rope was there as a bridge for something passing through the hole, and coming onto the bed.  Ã‚  There was no way in which the girl could prevent her death unless she moved rooms. There was also a saucer of milk in Dr Roylotts room to lure the snake back. The poison in the snake would not show up on any tests so the death could not be linked to the snake so no one would suspect the doctor. The crime was so well done that no one suspected Dr Roylott and nothing was said for years until Helen began to hear the same whistling sound and clanging sound as Julia. This crime was no where as neat the same as the murder in Lamb to the slaughter because the murder was not planned whereas in the speckled band it was. The murder was out of jealousy and madness. It was out of jealousy because Mrs Maloney couldnt face her husband with another woman because she loved him so much. It was out of madness because she couldnt believe that he was leaving her after what she has done for him. The murder in The speckled band was out of greed for money, which I will describe later. Mrs Maloney didnt mean to kill him she was just so mad and confused she just hit him with what she had in her hand. Mrs Maloney was also quite clever at covering up the crime because she put the murder weapon in the oven and cooked it and made the policemen eat it. She also went out to the grocers and acted very cheerful and told the grocer that she wanted to treat him and cook him a nice tea and pamper him because he was tired. She heard a few of the whispered phrases acted quit normalvery cheerfulwanted to give him a good supperpeascheesecakeimpossible that she  Mrs Maloney also told herself that when she set off from her house Patrick was alive and when she got back and found him dead that it would be a great shock to her so that she wouldnt have to fake her emotions. Mrs Maloney was very good at covering up the murder, acting very shocked and using the grocer as an alibi. This is similar to The speckled band because both murders were cleverly covered up.   When we studied the crimes we looked at why the murders would kill those people and we found out some motive of why they killed them. Once we had done this we compared them. In The speckled band Dr Roylott had an obvious motive, money. Money linked to inheritance. Julia, the girl who was murdered was due some money so if she died it would go to Dr Grimsby Roylott. Helen was also due some money linked to inheritance and again it would go to Dr Roylott if she died. His motive was money and greed. Julia was a typical victim as Dr Roylott was a typical villain. Julia was a young woman, innocent and venerable. Dr Roylott was a typical villain because he was violent, aggressive and had a previous record. What has she been saying to you? screamed the old man furiously.The doctor had a very unusual method of murder, snake, whereas in Lamb to the slaughter it was not as unusual.  In Lamb to the slaughter the motive was Mrs Maloneys husband was leaving her for another woman. Mrs Maloney was confused, jealous and angry. Mrs Maloney was and unusual victim because she was pregnant, the wife of a policeman very happy to be married to Patrick. The murder was impulsive and it maybe was manslaughter. When we had looked at the crimes and motives we then looked at the clues and red herrings which were given throughout the two stories. In The speckled band quite a lot of clues and red herrings are given. For instance when Helen Stoner came to Sherlock she describes that Julia was complaining of whistling and metal clanging sounds in the last few nights that she was alive. Also when Helen was forced to sleep in the room where Julia died she heard the whistling and clanging of metal sounds. Tell me, Helen, said Julia, have you ever heard anyone whistle in the dead of the night?  This shows that the whistling sounds and the metal clanging sounds are linked to Julias death. Some more clues, which were linked to Julias death was the vent which didnt leave outside it lead straight through to Dr Roylotts room. There was also a bell pull, which lead to no bell. The bell pull ran straight down to the bed, which was clamped to the floor. Helen also described that Julia always locked her door every night because the doctor kept a cheetah and a baboon. There was also bars in the chimney so no one could come down from the roof and the windows were very small and had shutters on which could not be forced open from the outside. After a careful examination through the window, endeavoured in every way to force the shutter open, without success.  Another clue given to you in The speckled band was that when Julia was found she was holding a match, which had been lit, in one hand and in the other hand she held a matchbox. Also just before she passed away she said,  O, my God! Helen! It was the band! The speckled band!  She pointed in the direction of the Doctors room after she said this.  When Holmes was examining Dr Roylotts room he noticed that he kept a large metal safe, a saucer of milk on top it and on the wall a dog lash. All these were very peculiar. A large iron safe was the principle thing that met the eye He took up a small saucer of milk which stood on top of it the object which had caught his eye was a small dog lash hung on the corner of the bed.  There are not just clues in The speckled band there are red herrings, things which send you in the wrong direction of solving the case. For instance a red herring in The speckled band are the peculiar pets which the doctor keeps, the cheetah and baboon. Another red herring is the gypsies, which camp on the Stoke Moran property. When Julia say that it was the speckled band Helen told Holmes that the gypsies wear head bands which are speckled so Holmes thinks that the gypsies have something to do with the death of Julia. This again is leading Holmes and Watson off the case. We then compared The speckled band clues and red herring with the Lamb to the slaughter clues and red herrings we found that they were very different. There were very little clues and red herrings in the story because the murder was unplanned and the story is a short one. Although there was some clues and red herrings within the story. The leg of lamb was the murder weapon but the police failed to notice this whereas Holmes found every clue there was in The speckled band. Already there are differences between the stories because the police didnt find any of the clues linked to Jack Maloneys death whereas Holmes found them all. As I said there were very little clues but there are quite a few red herrings, as there was in The speckled band. A red herring in the Lamb to the slaughter was that when Mrs Maloney went to the groceries acting very cheerful and happy as if there was nothing wrong. This is leading the police off from blaming Mrs Maloney for Patricks murder because she wouldnt be acting cheerful if she had just killed her husband. Mrs Maloney uses the grocers for an alibi, which suddenly throws the blame off her. Another red herring is the way Mrs Maloney acts in front of the police. When she was talking to the police she put on innocent eyes and an innocent face and tilted her head, which gave the impression that, she would never hurt anyone let alone her husband.

Essay Major Maturity

Essay Major Maturity Essay Major Maturity Torrey Hickel Honors Freshman English 1 Dr. Cobb 14 February 2013 Major Maturity Imagine you are in an 1840’s time period, with the power of women greatly suppressed and with romantics at an all time high. Picture being in the heart of the Victorian era with marvelous architecture paired with rich culture. That is the setting that Charlotte Bronte’s novel, Jane Eyre, takes place. The character development of the novel’s main character, Jane Eyre, takes place in three major settings, Gateshead, Lowood, and Thornfield. The novel first introduces Jane in the setting of Gateshead. She is portrayed as a neglected and abused 10 year old girl with her opinion and existence completely ignored. Gateshead is the home of Jane’s aunt and cousins, the Reeds. Jane feels hatred for all of the Reeds but especially her cousin John Reed. He abuses her very frequently, usually around twice a day and Jane has no choice but to accept the abusement. If she even complains about her treatment she will be punished greatly. â€Å"I saw him lift and poise the volume†¦ not soon enough the volume was flung and it hit me, and I fell striking my head against the door† (Bronte 13). This quote perfectly reflects the cruel and unusual punishment that Jane suffers at Gateshead. This quote shows only the physical punishment that she receives and not the mental aspect of her punishment. At Gateshead Jane is often put into solitary confinement in the horrifying red room. This following quote describes the red room from Jane’s perspective. â€Å"This room was chill†¦it was silent†¦ it was solemn because it was known to be so seldom entered† (Bronte 16). The time that Jane spent at Gateshead was very unpleasant and she feels hatred for all of the Reeds. The next progression in Jane’s maturity occurs at Lowood institution. Here Jane meets someone who will become a great friend of hers named Helen Burns. She also grows to become more socially active along with more independence and self-relian ce. â€Å"I saw a girl on a bench near; she was bent over a book in which I could see that the title was Rasselas† (Bronte 51). This quote describes the scene of when Jane and Helen first met. Their friendship over the next year or two would greatly increase to a point when Jane calls Helen the only true friend she had ever had. Miss Temple, a teacher at Lowood, is also a character in the novel that Jane Eyre becomes very fond of. â€Å"I can remember Miss Temple walking lightly and rapidly along our drooping line, and encouraging us, by precept, and example, to keep up our spirits† (Bronte 63). This quote shows the optimistic and positive personality that Jane and all of the students at Lowood enjoyed in Miss Temple. Jane not only finds friendship in Miss Temple, but also a

EPR - Essay Example The uniqueness of an ERP is that it can be implemented into large and small sized organizations alike. ERPs are divided into different modules like procurement, sales, marketing, etc. which makes it possible for an organization to implement only those modules that are descriptive of their business. Some of the widely known applications available off-the-shelf are my SAP by SAP, PeopleSoft by Oracle, Microsoft Dynamics by Microsoft and Sage ERP by Sage Group. Due to the popularity of 'free' technologies (paid by through advertisements), several open source ERP software are also available. ERPs have gained enormous popularity in the business world and are considered as a 'dream come true'. Thus by looking at the advantages it can be found out whether it is a good dream or not. (TechFaq, 2008) (Swartz and Orgill, 2001) A seller of cartons of steel nails gets an order through the customer service representative who forwards the request on the ERP system to the production department after checking all necessary customer information through the same ERP system. Procurement, Production and all other concerned departments see the same information and update it as its get completed. A route is created where the information is automatically sent to relevant departments who track it down till its completion and its sales to the customer through the Customer Relationship Management systems. The customer gets the carton of nails faster and with fewer errors while the company gets lower cost and tracking facility. Reality Check Enterprise Resource Planning (ERP) appears to be a 'dream come true'. These commercial software packages promise the seamless integration of all the information flowing through a company. Mostly companies implement ERPs to try to integrate the financial and customer order information, standardize and improve organizational processes, reduce inventory and standardize HR information (Koch, 2008). However hidden costs such as training,

Arizona Tewa Kiva Speech as a Manifestation of Linguistic Ideology Essay

Arizona Tewa Kiva Speech as a Manifestation of Linguistic Ideology - Essay Example (298) He reports that Tewa were a Pueblo Indian group â€Å"which removed itself from Spanish influence in 1700 by migrating to the eastern most of the Hope Mesas† (298) In order to maintain their distinct culture they 1) resisted linguistic borrowing from other languages and 2) were the only out migrating group to retain its’ language into the present. The language preservation has been achieved through the Tewa control of â€Å"kiva† speech which is the religious ceremonial speech common to all Pueblo societies. The instruments of control are 1) regulation by convention 2) indigenous purity 3) strict compartmentalization and 4) linguistic indexing of identity. Regulation by Convention Ritual performances rely on fixed prayer and song texts with no tolerance for innovation. This is also manifested in everyday speech preferences, for example by greeting formulae. Also in traditional stories â€Å"audience members and performers alike have a tradition which emplo ys stylized non-verbal accompaniment and uses familiar story telling conventions,† for example the repeated use of â€Å"ba† as a genre making equivalent to our â€Å"so they say†. Such conventions must be followed even if narrators chose to contextualize their stories for specific audiences, or the content and narrator are non traditional in order for audience acceptance Indigenous Purity and Strict Compartmentalization. The author reports that the Tewa have a strict prohibition against the inclusion of foreign words and non kiva Tewa words in kiva ceremonies. This he contends is prompted by the â€Å"need for stylized consistency â€Å" in a conventional liturgical speech level, rather than indicating xenophobia against foreign languages. (302) By a trickle down effect the prohibition against foreign words prevails in everyday speech patterns as well. There is also a strict compartmentalization in Tewa linguistic ideology with â€Å"kiva talk† strictly segregated from both foreign influence and everyday Tewa language in order to preserve its’ sanctity. While examination of linguistic data supports the conclusion that few foreign words have been incorporated into Tewa language, there is evidence of grammatical convergence. Linguistic Indexing of Identity The author states that in Tewa society â€Å"a person’s speech behavior expresses important information the speaker’s identity†. This relates to his or her positional rather than personal identity. For example, â€Å"a conventional component of public announcements is the explicit announcement by the chanter of his mediating status as spokesman.† (306) Conclusion Kroskrity concludes by claiming â€Å"linguistic ideology presents an account which captures the cultural unity of otherwise disparate linguistic norms† and justifies the opening quote of this summary.(311) Since in Tewa society both religious and political leadership is concentra ted in kiva ceremonies, their linguistic ideology provides an insight into how power and social control are exercised. The â€Å"Father Knows Best† Dynamic in Dinnertime Narratives Introduction This article â€Å"addresses gender asymmetry in middle class European American families through an examination of a simple social activity narrating ( a story or a report) over family dinner† on the basis of the Father Knows Best dynamic where father is typically set up to be primary audience, judge, and center of family members actions, conditions, thoughts, and feelings as was the case for this well known 1950s ( 101 )TV sitcom. In spite of more recent feminist ideology, this family power dynamic appears to still prevail. Methodology The author’s study focuses on dinnertime communication patterns of 7 two-parent families earning under $40.000 per annum between 1987 and 1989.( 102 ) Each family had a 5 year old child who

Rate of Reaction and Yield Conversion | Experiment

Rate of Reaction and Yield Conversion | Experiment At the outset, the objective of this experiment is to scrutinize the rate of reaction and the yield conversion. And the foremost principal that should be applied in order to determine both rate of reaction and yield conversion is material balance for batch reactions. As the experiment go on, students are supposed to perceive the factors catering the yield, rate of reaction and also the conversion. According to the hypothesis of the experiment, with the increment of ethyl acetate (reactant) from 0.1M to 0.2M the rate of reaction should gradually increase, leading to an augmentation of the rate of reaction as well as the conversion of sodium acetate from sodium hydroxide. Secondly, the theories that students must be acquainted with is, batch reaction, conversion, rate of reaction, conductivity yield and saponification. Saponification is an essential theory that drive the whole experiment, as it function by hydrolyzing an ester, forming a acidic salt and alcohol. With the absence of the pertinent knowledge of saponification, the experiment will not be successful. Thirdly, the modus operandi of the experiment, it comprises of 3 focal steps, preparation of reactant, experimental arrangement and procedure to be carried out during experiment. Students are to be particularly vigilant during the experiment, as reactant given, contain some perilous substances that are detrimental to human body. Subsequently, with the use of two different concentration of acetyl acetate during the experiment, the result and calculation of yield and rate of reaction could be analyzed. The result tabularize based on the two different concentration should show a vast divergence. The 0.2M of ethyl acetate should possess a higher yield and rate of reaction according to the hypothesis of the experiment. Before proceeding to the conclusion, students are supposed to go through some discussion on the experiment. The points to be discussed are namely preventative measure and the factors affecting the rate of reaction. As a final point, the conclusion, it concludes whether the hypothesis of the experiment corresponds with the actual experiment performed. Tentatively the conclusion should support the hypothesis of the experiment, which is, as the concentration of ethyl acetate increases, the rate of reaction and conversion also increases. (Singapore Polytechnic 2009) Material balance with chemical reaction 1. Introduction 1.1 Background Over the years, heaps of researches have been done to capitalize on the yield, conversion and increase the rate of reaction. These three factors are the point in which have close connection with the profit of the company. By increasing the yield it means more production generate with a standard amount of reactant used. As for rate of reaction, rationally, the faster the rate of reaction the greater the production rate within a certain period. During the experiment, batch process is employed as a medium for chemical reaction between sodium hydroxide and ethyl acetate to take place. The reaction produces sodium acetate and ethanol every thirty minutes, recording was taken every one minutes to note down the conductivity values. The whole process of obtaining the product from sodium hydroxide and ethyl acetate, consist of batch process, closed system, law of conversion and also saponification reaction. Batch process, is a process when a fixed charge of raw material is introduced and the products withdrawn before the cycle repeat. A closed system is a system where no material crosses the system boundary. As for The Law of Conservation of Energy it states that energy cannot be created or destroyed, but can change its form. Lastly For unsteady state process, it means, not all of the conditions in the process remain constant with time or the flows in and out of the system can vary with time. 1.2 Aim The aim of this experiment on material balance with chemical reaction is to allow students to employ the principle of material balance with chemical reaction for batch reaction by determining the yield, conversion and reaction rate. The purpose is to allow students to understand the change of reaction, when the concentrated NaoH react with ethyl acetate in a reactor as time passes by. With the knowledge of it, we will then be able to understand the saponification reaction of NaoH with ethyl acetate solution. 1.3 Hypothesis The hypothesis of the experiment is that during the Saponification reaction between NaOH and Ethyl acetate solution in the reactor, the concentration of NaOH would decrease due to the number of NaOH molecules being used for the reaction to produce sodium acetate. Furthermore, by increasing the concentration of ethyl acetate, the rate of reaction will also be increased 2. Theory 2.1 Introduction of Theory The role of the theory below is to give a more detailed explanations on saponification, batch process, conversion, yield, rate of reaction and conductivity, so that is can allow students to have a better perception on the experiment. 2.2 Batch Process Batch process is a process in which a fixed charge of raw material is introduced and the product is withdrawn before the cycle repeat. During the experiment, batch process is employed, as reactants are put in to the system for thirty minutes for reaction to take place. After which products are withdrawn and the apparatus used are sluice before another batch of reactant are introduced again. Owing to the change in concentration and production of new product, the reaction is categories under unsteady state. (Singapore Polytechnic 2009) 2.3 Saponification Saponification is defined as a process where ester is hydrolyzed, forming an acid salt and an alcohol. For this experiment, students are suppose to apply the knowledge they acquired on saponification and react ethyl acetate and sodium hydroxide and to produce sodium acetate and ethanol as the product of the reaction. Sodium acetate is form due to the displacement reaction which occurred during the overall reaction. The hydrogen in ester is displaced by the sodium ion in the sodium hydroxide, thus forming an acid salt; sodium acetate. The reaction is irreversible, hence once the product is formed, it cannot be re reacted to form the initial state of sodium hydroxide and ethyl acetate. However, reaction could be accelerated with the use of a strong acid (concentrated sulphuric acid) as the catalyst of the reaction. (Richard Hamner, Green Mountain Soap Company 2006) 2.4 Conversion Conversion is a technique, when a feed is converted to products. The term conversion can also be defined mathematically as percentage conversion. Percentage conversion is derived by dividing; moles of key reactant that react, with mole of feed introduced and multiply it with 100%. A 100% conversion is not likely to occur in the lab, this is due to the restrain of mechanism, which deprived the ideal conversion to transpire. (Singapore Polytechnic 2009) 2.5 Yield There are copious definitions for yield. The three generally prevalent definitions are yield based on feed, yield based on the reactant consumed and lastly yield based on the theoretical consumption of the limiting reactant. These three definitions are usually employed by chemical engineering industrial to guesstimate the yield of the products. Yield based on feed are exemplify to be; amount of desired product obtained, divided by amount of key reactant (limiting reactant fed). As for yield based on the reactant consumed, it is depict as; amount of desired products obtained, divided by amount of the key reactant consumed. Lastly as for yield based on the theoretical consumption of the limiting reactant; it is elucidate as; amount of product obtained, divided by the theoretical amount of products that would be obtained based on the limiting reactant if limiting reactant react completely. The usage of the formula varies from the given information. (Singapore Polytechnic 2009) 2.6 Rate of Reaction Rate of reaction is the speed of the overall reaction; it can be affected by temperature, conductivity, pressure, concentration surface area, and also catalyst. 2.6.1 Temperature Temperature will radically affect the rate of reaction. The collision of particles is determined by the energy a particle possessed. With a higher temperature, it will cater the particles to have a higher energy, hence increase the effectiveness of collision, and eventually resulting to a faster rate of reaction (Redspot Publishing 2005). 2.6.2 Pressure Pressure is defined as a condition of being compress. The increase of pressure will cater to a faster rate of reaction as the areas the particle have are smaller after compression. This therefore causes particle of be closely packet together which result to a higher frequency of collision between gaseous molecules. However, the increase of pressure is only applicable for gaseous molecules, as liquid and solid cannot be compressed (Redspot Publishing 2005). 2.6.3 Concentration Increases of concentration mean that the presences of particles in a specific volume have increased. While the volume/ space remained constant, the quantity of the particles increases, these instigate the frequency of collision to be higher, and also enhancing in the effectiveness of collision. This effect on particles collision will encourage a faster rate of reaction during the reaction (Redspot Publishing 2005). 2.6.4 Surface Area to Volume Ratio The bigger the size of the particles, the smaller the surface area for collision of particles, whereas, when the particles sizes are reduced, the chances of particles colliding in to each other will be higher. This is due to the increases in surface area of particles with it size are being reduce. Rate of reaction will therefore increases as frequency of collision increased (Redspot Publishing 2005). 2.6.5 Presence of Catalyst Catalyst is defined as a substance that is capable of reducing the activation energy of particles without itself taking part in the reaction. Therefore with the presence of a catalyst, particles will have a higher energy than the activation energy. These will lead to a higher frequency of collision and also the much more effective collision. Rate of reaction will gradually increases with more collision taking place (Redspot Publishing 2005). 2.7 Conductivity The conductivity values of sodium hydroxide is tantamount to the conductivity values of the solution, as the conductivity values of other reactants such as ethyl acetate, sodium hydroxide and ethanol are inconsequential. With the conductivity values of the solution ascertained, the concentration of sodium hydroxide in the reacting mixture can then be determined. The rate on how fast concentration of sodium hydroxide is depleting can that be easily achieved, by tabulating a graph (Copyright 2009 Russell Mainstream Supply Ltd) 3. Procedure 3.1 Preparation of Starting Reactant Before beginning with the experiment, students should go through and understand the Material Safety Data Sheet (MSDS) of sodium hydroxide and ethyl acetate. The understanding of the data sheet is imperative as, without apposite understanding on the chemical used, perilous hazard might occur. The procedure on handling and disposal of chemical must be habituated before the beginning of the experiment. Students are handling with highly acidic concentrated reactant, therefore, disposable glove and chemical goggles should be putted on at all time during the experiment. 500mL of 0.01M of sodium hydroxide solution and 500mL of 0.01M ethyl acetate was the concentration needed to be prepared for this experiment. 500mL of 0.01M sodium hydroxide are suppose to be prepared, to do so, measuring cylinder was used to measure the required volume of 0.01M NaOH and poured in to a 500mL volumetric flask. De ionized water is poured in to the 500mL mark on the volumetric flask for dilution purposes. To ensure a fine dilution, flask should be covered with stopper and shake to ensure solution properly mixed. Preparation of 500mL of ethyl acetate solution was done by pouring 250mL of de ionized water into a 500mL volumetric flask, followed by measuring the stock solution using a micropipettor and dispenses it to the 500mL volumetric flask. Top up solution up to 500mL mark, and cover it with a stopper and shake the solution to ensure solution is well mixed. Experimental Setup Conductivity meter 1-litre reaction beaker Magnetic stirring device Conductivity probe Reacting mixture Retort stand Procedure During Experiment As the preparation of the sodium hydroxide solution is completed, solution is poured in to the reactor with the reaction conditions adjusted to predetermined level. The reaction conditions are directly related to the overall reactions; hence the recording of the condition is essential. Examples of the condition are, temperature, stirring speed, concentration and volume of reactions. Before the stirring process inaugurate, ensure that the conductivity meter probe is positioned into the reacting mixture and a stopwatch is ready for timing purposes. Ethyl acetate is to be poured in to the reactor, and recording should start immediately. While the solution is being stirred in the reactors, conductivity values are recorded at a regular interval of one minute for thirty minutes. After thirty minutes, reactor is stopped and a magnetic rod is used, to remove the magnetic stir bar in the reactor. The conductivity probe is then withdrawn and sluiced scrupulously with de ionized water. As for t he product, it is being disposed into a plastic waste container. The experiment is to be repeated based on the experimental methodology discussed with lecturer. However, to ensure consistency of the experiment, all glassware is to be rinsed. Once all the experiment is accomplished, all the equipments should be properly cleaned and chemical used are to be disposed in to the plastic waste container. Finally waste will be send to W314 for proper treatment before discarding and glassware used should be placed back to original location. Result and Calculation 4.2 Determination of the Yield of Sodium Acetate Determination of the yield of sodium acetate is associated with the concentration of sodium hydroxide. In tandem with the given information on the concentration of sodium hydroxide, the molar ratio employed can be dexterously deciphered. From here, calculation to verify the yield can be facilely obtained by using the mole, which is calculated using the molar ratio of sodium hydroxide and ethyl acetate. Finally, utilize the formula of yield calculation and the determination of the yield of sodium acetate can be anatomized. 4.3 Yield and Rate of Conversion of 0.01M Ethyl Acetate Solution for 15 Minutes. Concentration of sodium hydroxide at one minute interval NaOH + CH3COOC2H5 à   C2H5OH + CH3COONa Theoretical Mole of NaOH = 0.01 X 0.5L = 0.005 mol Actual Mole of NaOH = 0.00156 X 0.5L = 0.00078mol Number of moles reacted = 0.005 0.00078 = 0.00422mol Conversion of NaOH= 0.00422/0.005 X 100% = 84.4% Theoretically, since 1 mole of NaOH react and form 1 mole of CH3COONa, actual mole of CH3COONa= 0.00078 Yield of CH3COONa= 0.00078/0.005 =0.156 4.4 Yield and Rate of Conversion of 0.02M Ethyl Acetate Solution for 15 Minutes Figure 4.4.2.

Graph shown above is straight line. Gradient= 0.00275 0.00125 à · 20 1 = 0.0000789 (From the graph) 5. Discussion 5.1 Factors Affecting Rate of Reaction As indicated above, there are numerous factors that are capable of affecting the rate of reaction however; the only applicable one is the differences in concentration as the rest (temperature and pressure) are kept constant. Based on the experiment did, as the volume and concentration increases, the rate of reaction also increases, this is   by virtue of the presence of more particles in the solution, hence increasing the chances of particles colliding to each other, which eventually result in an increase in the rate of reaction. Below is a graph to further elaborate on the explanation on the difference in concentration. The judgment on the rate of reaction is based on the steepness of the graph. As shown, the black line which contains 0.02M of ethyl acetate has a slower rate of reaction as compared to the one in red which is 0.01M of ethyl acetate. This repudiated the hypothesis of this experiment. The dialectics of this contradiction is, there might be source of contaminant on apparatus or solution used. 5.2 Factors Affecting Conversion and Yield The ideal rate of conversion and yield will never be actualize under school environment or even in industries. As, in school students are using eye sight as a gauge for the experiment which indubitably cause error due to parallax error, as for industries, despite being able to afford high cost machines and computer, the cunctation between human and machines will cause an slight differ on the rate of conversion and yield. 5.3 Factors Affecting Conductivity Values As mention on the theory section, the conductivity values of ethyl acetate are imperceptible; therefore the conductivity rate of sodium hydroxide is employed instead. During the experiment, 2 different concentration of ethyl acetate was used. The first set of experiment, we used a concentration of 0.01M. It produces a constant decreasing rate at every one minute interval. This shows that while the moles of sodium hydroxide are depleting, conductivity value to decreases too. As for the second set of experiment, the same things occurred but at a same rate as the first set of the experiment. This contravene the theory, as suppositionally, the increases in concentration to 0.02M will cause the moles of sodium hydroxide to deplete at a faster rate, which result to a faster decreasing rate for conductivity. Again, the dialectics of this contradiction is, there might be source of contaminant on apparatus or solution used. 5.4 Precaution in Experiment As we all know, ethyl acetate are very volatile, it release harmful gas when it is expose to the environments. Therefore, adding of ethyl acetate into the volume metric flask must be carried out in the fume hood to prevent students from inhaling gases produced from ethyl acetate, which is harmful to human body. In addition, safety goggles and rubber gloves should be worn at all times during the experiment. This help to prevent students from having direct contact with the acid which might cause skin irritation of temporary loss of vision. 5.5 Comparison of Two Different Tests As two different concentrations were employed during the experiments, the result on yield and conversion rate will be different. 5.5.1 Comparison of the Yield of Two Different Tests Upon completion of experiments, the differences in yield were realised. The yield of 0.01M ethyl acetate was 0.156 and the yield of 0.02M ethyl acetate is 0.085. Theoretically, due to the increment in concentration, the yield of 0.02M of ethyl acetate should be higher as, since more reactants is used; it will rightfully result in more products being formed. However, as mention above, there might be chances of the reactants or apparatus used being contaminated, which result in the huge differences between the yields. 5.5.2 Comparison of the Conversion Rate The conversion rate of 0.01M of ethyl acetate was 84.4% and the conversion rate of 0.02M of ethyl acetate was 91.5%. The result shown was excellent, as high conversion rate will mean that, majority of the reactant was fully utilized, hence saving cost. 6. Conclusion Based on experiment, I can construe that the higher the concentration of ethyl acetate, it will result to a much faster rate of reaction, and a higher rate of conversion. The conductivity value is interred related and proportioned to the concentration of sodium hydroxide. Therefore, since observation and hypothesis are similar, the hypothesis is true. The aim of the experiment are also fulfilled, as scrutiny of the experiment have verify that, while the concentration of ethyl acetate got higher, the rate of reaction and rate of conversion increases. In addition, adding of catalyst or increasing surrounding temperature could also result in a faster rate of reaction which tantamount to an increment in rate of conversion.

Innocence in The Boy in the Striped Pajamas by John Boyne :: John Boyne, The Boy in the Striped Pyjamas

"The Boy in the Striped Pajamas" explores the beauty of a child's innocence in a time of war: Bruno, an eight year old boy at the time of the war, is completely oblivious to the atrocities of the war around him - even with a father who is a Nazi commandant. The title of the book is evidence to this - Bruno perceives the concentration camp uniforms as "striped pajamas." Further evidence is the misnomers "the Fury," (the Furher) and "Out-With" (Auschwitz). Bruno and Shmuel, the boy he meets from Auschwitz, share a great deal in common but perhaps what is most striking is the childhood innocence which characterizes both boys. Bruno is unaware that his father is a Nazi commandant and that his home is on ther periphery of Auschwitz. Shmuel, imprisoned in the camp, seems not to understand the severity of his situation. When his father goes missing, Shmuel does not understand that he has gone to the gas chamber. However, there is another facet to this beauty: "Where ignorance is bliss, 'tis folly to be wise" - so says Thomas Gray. In reference to this novel, it means that the people that lived in the vicinity of the concentration camp claimed to not know what was going on in the camp, so they could be "blissfully ignorant" of the Holocaust happening around them. This means that they did not have to live with the guilt of knowing what was going on and not doing anything. That is why they would be called "blissful". The quote means that if we are ignorant of something, we don't have to deal with it and are therefore happy. Remote African tribes, for example, are ignorant of the terrible wars going on elsewhere on their continent. So, they are happy. They are ignorant, and they are blissful. In the modern world, there are few places where this situation exists anymore, however. So, too, in World War II. We didn't have the Internet then, but there were other ways to find out what was going on in Nazi Germany. Do you think it is feasible that the Germans did not know what was going on? Do you think they were "blissful" because they were ignorant of the situation? A lot of them tried to claim this after the war was over. "We didn't know!" Most people do not buy this. How could they not know? Come on! The stench of burning bodies was everywhere.

Biblical Similarities in Hawthorne’s “Rappaccini’s Daughter” Essay

Biblical Similarities in Hawthorne’s â€Å"Rappaccini’s DaughterIn Nathanial Hawthorne’s â€Å"Rappaccini’s Daughter,† many biblical parallels can be found. This short story duplicates the first three chapters of Genesis in the Bible. The similarities range from the characters, to the setting, and even to the deadly plant in the story. The account of Adam and Eve in Genesis chapters 1-3 is extremely similar to the situation of Giovanni and Beatrice in â€Å"Rappaccini’s Daughter†. In both â€Å"Rappaccini’s Daughter† and the Genesis chapters in the Bible, lush, beautiful gardens are the setting. Both gardens are exotic and pretty, but the Garden of Eden is bright and tropical, whereas Dr. Rappaccini’s garden is dark and mysterious. Both gardens are home to a type of â€Å"forbidden† plant, but the Garden of Eden was created by God, whereas the garden in the story is created by a man with a god complex, Dr. Rappaccini. The forbidden plant in Genesis is a gorgeous fruit tree. The tree in the Garden of Eden is called the Tree of Knowledge and was extremely tempting to Adam and Eve. However, the tree was deemed prohibited by God. The plant in Rappaccini’s garden is a large flowering bush. The flowers on this bush are unlike any others and are extremely exquisite. The two plants share the trait of â€Å"forbidden,† but in different ways. The fruit on the tree in Genesis was forbidden because God said so. The plant in Rappaccini’s garden was forbidden because it was poisonous. The only person immune to the poison of this plant was Beatrice, then soon Giovanni. In Hawthorne’s story, a parallel between Giovanni and Adam is established. Both are young men, and each were tempted by a beautiful young woman. Giovanni in Hawthorne’s story was lured into the garden by Beatrice’s beauty. Adam was lured by Eve’s beauty to betray God. Beatrice and Eve also share similarities. They both are beautiful and young and are naà ¯ve to the evils of the world they live in. The serpent in â€Å"Rappaccini’s Daughter† is clearly represented by Dr. Rappaccini and Professor Pietro Baglioni. Dr. Rappaccini is responsible for luring Giovanni into the garden for his daughter, and also for exposing him to the toxin that led to him becoming like Beatrice, poisonous and stuck in the garden. Professor Pietro Baglioni is responsible for giving Giovanni the silver vial with the supposed antidote for the poisons. When Giovanni gives Beatrice the vial she then dies because the poison is too entwined with her body. Sadly, she was not given a second chance like Adam and Eve. The story of â€Å"Rappaccini’s Daughter† is an extremely enjoyable story with close biblical ties. The parallels are extremely apparent and also very important. What seems to be a story simply of fatal love is quite possibly a retelling of the opening chapter of Genesis in the Bible.

Edvard Griegs Morning Mood Hall of the Mountain King essays

Edvard Griegs Morning Mood Hall of the Mountain King essays When one thinks of the Romantic composers, the names Beethoven, Wagner, Chopin, or Liszt come to mind. Looking even further into the period one sees the names of nationalist composers like Glinka, Tchaikovsky, and Smetana. Unfortunately, there are still many composers of the Romantic era whose music is known, but for some reason there names have grown apart from there music. Edvard Grieg, a Norwegian nationalist composer, is one of these men. Many people would know Griegs work In the Hall of the Mountain King if they heard it, but would be unable to tell you who had written it or where the work originates from. Despite his lack of fame in todays world, his music still is a prime example of the Romantic period and tendencies. Two works in particular are Morning Mood and In the Hall of the Mountain King, both from his Peer Gynt Suite No. 1, despite their very conflicting styles Edvard Grieg is thought of in the music field as a symbol of Norway. He was born in Bergen, Norway on June 15th, 1843 the fourth of five children. Music interested Grieg from a young age and at the age of six he began piano lessons with his mother. His mother, Gescine Hagerup, was known as the best piano teacher in Bergen and led him firmly, but lovingly into the music field. At the age of fifteen in October of 1858, Grieg left to attend the Leipzig Music Conservatory. He did not have an easy time at the conservatory. During his time there, Grieg suffered an attack of pleurisy that caused permanent damage to one of his lungs. He also had problems with the institutional nature of the school. However, despite the hardships he faced, he graduated from Leipzig at Easter in 1862 with high marks. After graduation, Grieg moved to Copenhagen to broaden his musical scope. While in Copenhagen he met people that would become life long friends and idols. One of Griegs first idols, which he met in...

Economics and the environment essays

Economics and the environment essays Before if someone would have used the words economics and the environment in the same sentence I would have looked at them with a dumbfounded expression on my face, however the basic principles of economics can be applied with great benefits of the environment. An example the speaker made was with African Elephant populations in two separate countries, one country outlawed the hunting of the elephant while the other country gave private ownership to the elephants and legalized trade on the elephants and the products that could be made from them. Since I had no knowledge of economic principles, I expected the country that outlawed the hunting to have the greater population, but in reality the country that gave personal ownership had nearly double the population of elephants after ten years. This was explained to us by the concepts of benefits, if you can make money off something, you are more likely to do it. The towns raised the elephants similar to how we raise cows. The next example that was given was the incorrect (for the environment) usage of this concept. There is a species of woodpecker that will only nest in a single type of maple tree, so the government passed a law that anyone with one of these trees with a nest in it could not build on the land in a hundred foot radius of the tree and would be fined greatly for doing so. This lead to the mass destruction of the poor birds habitat, as most of the nation cut down these trees to avoid these birds, which would lead to their extinction. The speaker (Russel Sobil) was very talented and appeared to be extremely competent on this subject matter, which I found out I knew nothing about. I found this lecture interesting, and it also raised my interest in this subject matter. ...

Poem Explication Essay Example | Topics and Well Written Essays - 500 words

Poem Explication - Essay Example There are six stanzas in it, but none of them follow traditional poetic forms or a set meter. Instead, Hughes allows the lines to be choppy, like how he imagines a hawk might think. The animal's self-impression is given as he seems to judge his body, "on falsifying dream / Between my hooked head and hooked feet: / Or in sleep rehearse perfect kills and eat" (2-4). The thoughts are presented as fragments only loosely connected to each other. As the hawk surveys his land through these choppy thoughts, it becomes clear he considers himself the master of his domain, â€Å"Nothing has changed since I began. / My eye has permitted no change. / I am going to keep things like this† (22-24). The mind of the hawk is flighty, but shows two primary drives -- an appreciation for beautiful detail and a deadly purpose. Hughes demonstrates a strong understanding of the hawk's world as something that is both beautiful and terrible. He says, "the earth's face is upward" (8) as he talks about th e trees poking into the sky, the buoyant air of the mountain and the warm sunshine. These details bring to mind a beautiful spring day glittering with promise.
